I'm pretty new to mac, and I only know them as intel machines, so I'm a little clueless here. I'm considering purchasing a mac pro to use as a server and I don't need a huge amount of horsepower. From a technical point of view a G5 will do me just fine. But what I'm not sure of is what I might be missing in running a PowerPC rather than intel. Is there certain software that won't run on the old hardware, or any other incompatibilities I need to be aware of? Thanks in advance.
